SILO.

Application led April 8, 1911. Serial No. 619,759.

To all whom it may concern.' v

3e it known that I, EDWARD KRETCHMER, a citizen ot' the United States. residing at Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented new and useful Improvements in Silos, of which the following is a specification.

This invention relates to silos, the object of the invention being to provide a device of this character that is adapted to serve either for t-he storage of grain or ensilage, one that will be very easy to erect, that will be rigid and solid when erect-ed, and will be very durable and easy to repair, if repairs are necessary.

-l further and very important object of the invention is to provide a silo so insulated against heat and cold as to protect the contents thereof from the .heat of the sun or from excessive cold weather. and further, to prevent the leaking of the juices of the ensilage. j

Further objects and advantages of the invention will be set forth in the detailed description which now follows:

Figure 1 is 'a perspective view of a silo constructed in accordance with the invention, parts of the walls having been broken away to expose the interior construction. Fig. 2 is a horizontal sectional detail view taken on the line 2--2 in Eig. 1. Fig. 3 is a sectional detail view of a portion of one of the rings employed inthe construction of the silo, and showing'the laminated construction thereof.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing, the numerals 5 designate a plurality of horizontally disposed annular members, each of which is made up of a plurality of horizontally dis posed laminations or strips 5a. These rings are spaced apart by vertically disposed bars G which, together' with the rings, constitute the framework of the silo.

The inner wall of the silo comprises a lining preferably of roofing felt indicated at 7. Over this, upon the inside of the structure, tongue and groove boards fitted closely together are nailed, these boards being indicated at 8. If desired. a coating of cement indicated at 9 may be placed over these boards after the structure is completed. To hold the felt securely in place,'wires 1() are passed around the structure and bind this felt firmly against the boards 8. The outer ISpecification of Letters Patent.

`metal plates 12.

Patented Feb. 6', 191e..

wall ofthe silo comprises a lining of roofing felt 11 and a covering of galvanized sheet In putting this outer wall inposition, the first strip of roofing felt is fastenedl horizontally to the next to the bottom annular member 5, lapping down over the bottom annular member. The n eXt higher lining strip is puton after the lowest galvanized sheet metal band or strip `is in place, the lower edge of each strip of this lining, felt lapping a few inches over the upper edge of the galvanized sheet metal strip next below, so that when the second and subsequent galvanized sheet metal strips are in place, the lower edge of the felt roofing strips are between the overlapping edges of the galvanized sheets. thereby' forming a packing. lVhile I prefer to use galvanized sheet metal strips or plates for the outer wall, it is of course to he understood that ,any other material may be used for this purpose. v

The upper edge of each of the sheets 12 is inwardlyT flanged at l?,v and when put in place. this flange 13 overhangs the upper p side of the annular member adjacent which itv is located and bears upon said annular member. The lower edges of these plates are preferably corrugated and slightly in- "wardly directed. Metallic bands or hoops 14 extend around the body of the silo over each of the joints between the sheets .12, these bands being provided with draw-lugs and screws 15. by means of which the bands are securely bound in place. When these bands are tightened, it is apparent that. the

lower corrugated edges, ofthe plates will be forced snugly against the upper portions of the plates that they overlap, binding the lower edges of the. roofing felt strips be tween these plates and making a snug and tight joint. This renders the space between the inner and outer walls of the silo a deadair space which serves as an effective insulation to protect the contents of the silo from excessive heat or cold.

Between certain of thc vertical strips 6,

doorways or openings 16 are left. these doorways being adapted to be closed by doors 17. TheseA doors are constructed of inner portions 18 of tongue and grooved boards which run horizontally'across the openings forming the doorways 16 and lap several inches on each side thereof to engage behind the sides. top and 'bottom of said doorways. Over these portions 19 is placed a lining `preferabl of roofing felt, then two vertical ing forming the doorway when the door is in position. Over these cleats, 'another layer of roofing felt 20 is placed and then a galvanized sheet 21 is nailed upon said cleats over the last named layer of felt. Bears 22.

are pivotally mounted at 23 upon blocks 24 secured to the outer faces of the doors, these bars being adapted to lock the doors in their closed position, as will be readily undersack, Aor other receptacle. ledges of the sheets 12 to the vertical door stood, by engaging the vertical side posts of p the doorway. Binding members 25 are 'threaded upon bolts 26, upon which bolts the bars 22 have their pivotal mounting and vserve when rotated to draw the doors toward the bars 22, whereby these bars may be very securely and tightly fastened in place. The

v structure set forth with relation to the doors renders these doors insulators against heat and cold. v y v-Virhen the 'device is used as a storage fre-- ceptacle for grain, a chute 27 is employed.

Thischute is held by links 28 and is adapt-` ed to ,be brought into alinement with lan opening 29. This opening is controlled by a slide 30 and when the slide is moved to uncover the opening, it iis apparent that the grain will pass out into the chute' from whencel it may be conducted inv a wagon, -To secure the posts 6, strips of iron 31 are secured to the 'outer faces of the door posts 6 over the ter-l minal edges of the said sheets.

. From the foregoing description, it will be lseen that 4simple vand ellicient means are herein provided for accomplishing the objects of the invention, but while the 'elements shown and described are we ll adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited 'to the precise construction set forth, but includes within its purview such changes as may be made'within the scope of the appended claims.

Having described my invention, what I claim is: l
